1,386,356. Specification of 1mm huntl atented Aug. 2, 1921. Application filed January 19, 1920. Serial No. 852,470. To all whom it may concern: units illustrating the means of connecting Be it known that 1, WILLIAM E. PASIK, a citizen of the United States, residin at De Kalb, in the county of De Kalb and tate of Illinois, have invented certain new and useful Improvements in Electric Heaters, of which the following is a specification.

This invention relates to electric heaters, and the primary object of the invention is to provide an improved electric heater of the radiator type in which a maximum amount of heat radiating surface is provided, so as to permit the quick and thorou h heatin of a room or the like.

nother 0 ject of the invention is to provide an improved electric heater embodyin a plurality of heat radiatin units arranged in spaced relation so that t e air can circulate around and between the same and thereby effect the quick heating of the surrounding atmosphere.

A further object of the invention is to provide an improved electric heater having a plurality of spaced heating elements each including a resistance wire positioned in a hollow heat radiating member having alarge area of radiating surface for warming the surrounding air.

A further object of the invention is to provide an electric heater of pleasing apearance which can be easily transported om one room to another and which is adapted to be connected to the ordinary electric light socket.

A still further object of the invention is to provide an improved electric heater of the above character, which is durable andefiicient in use and one that is simple and easy to manufacture, and one that can be placed upon the marketat a reasonable cost.

Other objects of the invention will appear in the following detailed description,

taken in connection with the drawings, forming a part of this specification, in which drawings:

Figure 1 is a side elevation of the electric I heater.

Fig. 2 is .an end elevation of the same partly in section.

Fig. 3 is a longitudinal section through the same, taken on the line 3-3 of Fig. 1.

Fig. 4 is a fragmentary vertical transverse section through the heater.

Fig. 5 is an enlarged fragmentary detail vertical section through one of the heating assembling the device the resistance wire 12 is first placed in one of the lugs 13, which the same to the connecting plate.

. Flg. 6 is a fragmentar vertical section lllustratin the meansof astening the connect ng p ates together, and

Fig. 7 is a diagrammatic view of the electric wire for the heater.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A indicates the improved electric heater which includes the heating units B and the u per and lower connecting members C and v The heat units B are arranged in spaced lon itudinally extending rows, and each inolu es a hollow pipe formed of iron or the like, which can be, if so desired, provided the pipe 10 recelve porcelain plugs 13, which 85 are held against displacement by suitable screws or the like 14 which extend through the pipe into the plu T e outer terminals of the plugs 13 are provided with outwardly flared heads 15, which serve as means to connect the pipes 10 with the upper and lower connecting members C and D.

The upper and lower connecting members C and Dare constructed identically the same and each include an outer plate 16 and an inner plate 17. The plates 16 and 17 of the upBer and lower connecting members C and are formed substantially rectangular in shape and are connected together by suitable nuts and bolts 18, the heads of which are countersunk as at 19. Each of the inner plates is provided with ta cred opening 20 for the reception of the ared heads 15 of the porcelain plugs 13 and in is provided with a slit for t e rece tion of I the same, and the flared head of the plug is placed in the tapered opening 20 in theme porcelain 'After all of the h'eating units are laced in ition on the inner plates 17, e outer plates 16 are placed in t1on and held against displacement by e bolts 18. The

outer plates 16 prevent displacement of the plu 13 from the inner plates 17 As stated, the plates 16 and 17 are formed of insula material and the connecting portions 21 or the heating un 1ts 12 are positioned between the plates.

As clearly shown in Fig. 7 of the drawings, the lead wires 22 and 23 extend into the lower connectin section C and the lead wire 22 is connector? to one row of the heatunits which is connected to the intermediate rows as at 24, the forward end of which is connected in turn to the outer row as at 25. The lead wire 23 is then connected as at 26 to the rear end of the outer row. Thus it will be seen that all of the heating units are connected to ther in series. The outer plug 17 of the ower connectin section D is provided at its corners wit enlarged bases 27, which have secured thereto by suitable screws or the like 28, Iron feet 29 which form suppozts for the radiator.

The lead wires 22 and 23 have inter therein a suitable push switch 30 so that the construction which has a relativel heater can be turned on or ofl without disconnecting the plug 31, which is of the ordinary or any preferred type from the electric socket (not shown).

From the foregoin description it can be seen that an improve electric heater is provided of exceptionally durable and siinple ar e area of heat radiating surface, so t at t e surrounding atmosphere can be efiiciently and readily heated.

Changes in details may be made without departing from the spirit or scope of my invention; but,

I claim:

1. In an electric heater, a hollow cylindrical metallic body, a sleeve of non-electric conducting material arranged in the body, and a longitudinal electric resistance the outer ranged between the sections, each of the sections inclu inner and outer plates, the inner lates aving oppositely extending tape sockets formed therein, each of the heat radlat' units including a hollow body porcelam lugs carried by the termm). of the y, flared heads formed on the plugs and extendi beyond the body and arranged to fit in t e tapered sockets, resistance wires carried by the plugs and arranged in the body, the outer plates of the sections bemg adapted to overlie the sockets and enga the enlarged flared portion of the porce ain plugs and means for securing lates to the inner plates.

4. An e ectric heater comprising upper and lower sections, heat radiating units ar ranged between the sections, each of the sections includin inner and outer plates, the inner lates aving op ositely extending tapers sockets formed t erein, each of the posed heat radiating units including a hollow cylindrical pipe, a sleeve of insulating material arranged in the pipe, porcelain lugs carried by the termina s of the pipes, ared heads formed on the plugs and arranged to fit in the ta red sockets, the resistance wires carried y the lugs and arranged in the body in spaced re ation to the insulated sleeve, means connecting the resistance wires arranged intermediate the inner and outer plates of the sections whereby displacement of the wires is prevented, the outer plates of the sections being adapted to overlie the sockets and arranged to engage the outer surface of the enlarged flared faces of the porcelain plugs, to prevent displacement thereof from t e sockets, and means for detachabl securing the outer plates to the inner p ates.
